- Keuffel & Esser Co.
- Description
- This ten-inch one-sided wooden slide rule is coated with white celluloid. The indicator is glass with white plastic edges attached by metal screws. The base has A, D, and K scales. The slide has B, CI, and C scales on one side of the slide and S, L, and T scales on the other side. The top and bottom edges are beveled; the top has a simply divided scale 10 inches long and divided to sixteenths of an inch, while the bottom has a simply divided scale 25 centimeters long and divided to millimeters.
- The left end of the slide has the model number in red: 4053-3. The right end is marked in red: © (/) K+E. The left end of the back of the slide has a serial number: 169518. Underneath the slide is marked: KEUFFEL & ESSER CO.; MADE IN U.S.A. Engraved directly on the back of the rule are tables of measures labeled: CONVERSION FACTORS. Centered underneath the tables is: KEUFFEL & ESSER CO.
- Keuffel & Esser made slide rules of this type from 1909 to 1967. McCoy notes that this version of model 4053-3 (with this model number and the engraved tables) was introduced in 1954. In 1959, the rule sold in a plain case for $13.50. In 1962, model number 4053-3 was changed to 68-1622. The serial number suggests a date closer to the late 1950s than to the early 1960s. Compare to the earlier rule, 1981.0933.05.
